    We define K-theory for Fréchet algebras (assumed to be locally multiplicatively convex) so as to simultaneously generalize K-theory for σ-C*-algebras and K-theory for Banach algebras. The main results on K-theory of σ-C*-algebras, which are analogs of standard theorems on representable K-theory of spaces, carry over to the more general case. From Wikipedia, the free encyclopedia In mathematics, especially functional analysis, a Fréchet algebra, named after Maurice René Fréchet, is an associative algebra {\displaystyle A} over the real or complex numbers that at the same time is also a (locally convex) Fréchet space.

    The result stated in the title is proved in a Banach algebra and is used to discuss (i) commutativity criteria in normed algebras, (ii) uniqueness of the uniform norm in uniform Banach algebras.   We say that Hol(G) separates the points of G. Pointseparating subalgebras of C(X), X a a-compact and locally compact space, which are complete with respect t o the compact open topology w i l l be called uniform Frechet algebras, cf. (). Hence Hol(G) is a uniform Frechet algebra.

    The uniform Banach algebras and the commutative B*-algebras are examples of Banach algebras where F is isomorphically isometric to,~ under the Gelfand transform (see [16, ], and [18, 4. The theorem on the surjection of Fréchet spaces is an important theorem, due to Stefan Banach, that characterizes when a continuous linear operator between Fréchet spaces is surjective.. The importance of this theorem is related to the open mapping theorem, which states that a continuous linear surjection between Fréchet spaces is an open in practice, one knows that they have a.

Uniform Frechet algebras. [Helmut Goldmann] -- The first part of this monograph is an elementary introduction to the theory of Fřchet algebras.

Important examples of Fřchet algebras, which are among those considered, are the algebra of all. The present book is devoted to the detailed study of uniform algebras. In addition to using methods and results of the theory of Banach algebras (the structure of the space of maximal ideals), the theory of uniform algebras is related to the theory of analytic functions, so that some of the deepest results about uniform algebras involve.

A Banach algebra A is called a uniform Banach algebra (uB-algebra. A non-Banach uniform Fréchet algebra with a power series generator is a nuclear space.

A number of examples are discussed; and a functional analytic description of the holomorphic function. This chapter discusses uF-algebras that are Schwartz spaces.

These algebras are called “uniform Fréchet–Schwartz algebras (uFS-algebras).” uFS-algebras are reflexive uniform Fréchet algebras (uF-algebras), and they are stable with respect to the formation of Hausdorff quotients.

Publisher Summary In an analogous way to the theory of Banach algebras (B-algebras), this chapter discusses uniform Fréchet algebras (uF-algebras) and presents equivalent characterizations. Hopf algebra actions on differential graded algebras and applications He, Ji-Wei, Van Oystaeyen, Fred, and Zhang, Yinhuo, Bulletin of the Belgian Mathematical Society - Simon Stevin, ; Extensions of uniform algebras Morley, Sam, Banach Journal of Mathematical Analysis,   An important subject in the theory of Fréchet algebras is the question of the existence of analytic structure in spectra.

The detailed study of this problem for uniform Fréchet algebras is discussed in, especially the work of Brooks, Carpenter, Goldmann and Kramm. Very rarely is it possible to give an analytic structure to the whole spectrum and therefore it is of interest to know conditions which ensure that parts of the spectrum of a Fréchet.

This text is a classical reference on uniform algebras, written by a major expert in the area. Gamelin's book is a nice text that any mathematician interested in uniform algebras or related questions should have on his shelves. The book is also interesting for non-specialists.

Uniform Frechet algebras. By H Goldmann. Abstract. The first part of this monograph is an elementary introduction to the theory of Fréchet algebras.

Important examples of Fréchet algebras, which are among those considered, are the algebra of all holomorphic functions on a (hemicompact) reduced complex space, and the algebra of all continuous Author: H Goldmann. Compactness, non-emptiness and polynomial convexity of the left spectrum, coincidence of left and right spectra, and countably generated uniform Banach algebras are also discussed.

View Show abstract. Uniform Fréchet algebras (uF-algebras) have been extensively investi- gated by Kramm (see references in [6] and the forthcoming book by Goldmann [3]) in view of recapturing holomorphy through a functional analytic approach.

Definitions. Fréchet spaces can be defined in two equivalent ways: the first employs a translation-invariant metric, the second a countable family of semi-norms.

A topological vector space X is a Fréchet space if and only if it satisfies the following three properties. It is locally convex.; Its topology can be induced by a translation-invariant metric, i.e. a metric d: X × X → R such. COVID Resources.

We prove that every compact homomorphism between uniform Fréchet algebras actually ranges into a uniform Banach algebra, and that its spectral adjointmaps τ-bounded subsets into relatively τ-compact subsets, when τ is the strong or the compact .
